Three Laws of Thermodynamics

Thermodynamics-the study of conversions between thermal energy and other forms of energy.Absolute Zero-or zero degrees kelvin is the tempurature where all motions stop.Entropy- is commonly understood as a measure of disorder.Temperature- is the measure of the average kinetic energy of the atoms in an object.

Heat-is the transfer of energy from one object to another because of a temperature difference.Calorie-A unit of heat and energy equal to the amount of energy requires to raise the temperature of one gram.Energy-is the ability to do work.Potential Energy- energy that is stored as a result of the position or shape.

Kinetic Energy-the energy of motionExothermic- formed from its constituent elements with a net release of heat.Endothermic-accompanied by or requiring the absorption of heat.Thermal Expansion-is an increase in the volume of a material due to a temperature increase.

Thermal Contraction-materials expand it contract when subjected to change in temperature.Radiation-the transfer of heat or energy by electromagnetic waves.Convection-is the transfer of energy through the motion of currents in fluids. Such as liquids and gases.Conduction-is the transfer of energy through solids of different temperature by direct contact.
